Hello! I'm currently working on an extension for the document exchange service, and i'm having a bit of trouble with oauth.
I'm at a point where i can successfully extend "Doc. Exch. Service Setup", to add my own links for signup, signin, etc. My issue is that, when I go to activate the service, my redirect to business central (with a generated code and the proper status as query arguments), fails with http 400. There's no additional data in devtools, and i can't seem to find any documentation for this, as the only oauth2 documentation appears to be for client application, while i'm acting as a server here
